Change Healthcare Hackers Received a $22 Million Ransom Payment

Change Healthcare, a unit of UnitedHealth Group, was the victim of a ransomware attack by the group ALPHV, also known as Blackcat. The attack has led to billing delays and security concerns. The breach has affected billing and care-authorization portals across the country. The company is assessing the impact of the attack, which it first acknowledged on February 21. The attack could also disrupt discharging people from the hospital and delay some prescriptions and paychecks for medical workers. The company did not respond to a question about whether it paid or negotiated a ransom. The severity of the situation may still be unfolding.
